2 Claims. 1

This invention relates to a clamp for securing the spare tire and wheel of an automobile or the like.

Automobile spare tires and wheels normally are held in place in the trunk compartment by a bolt and nut arrangement which is inconvenient to operate and requires substantial time for operation. An object of this invention is to provide a quick operating clamp which holds the spare tire and wheel firmly in place in its mount but which can quickly and easily be opened to release the tire and wheel or closed to secure the spare tire and wheel in its mount.

The size and iniiation of a spare tire may vary during use. A further object of this invention is to provide a clamp which can quickly and easily be adjusted with the size and inflation of the tire to hold the tire in place, both when the tire is fully inflated and when it is partially cledated.

A further object of this invention is to provide a quick operating clamp which engages and grips the spare wheel at the hub opening thereof to secure and hold the spare wheel and tire in place.

The 'above and other objects and features of the invention will in part be apparent and will in part be obvious from the following detailed description, and the drawing, in which:

Figure 1 is a view, partly in section and partly in side elevation, showing a spare tire and wheel mounted in a vehicle, the spare tire and wheel being held in place by ra clamp constructed in accordance with an embodiment of this invention;

Fig. 2 is a view in section taken along a line II-Il in Figure l;

Fig. 3 is a View partly in section and partly in elevation, showing a clamp constructed in accordance with another embodiment of this invention, the clamp being shown in engagement with a wheel, only a fragment of the wheel being shown;

Fig. 4 is a view in section taken along a line IV-IV in Fig. 3; and

Fig. 5 is a view partly in side elevation and partly in section, showing a sector plate which forms a part of a clamp constructed in accordance with another embodiment of this invention;

In the following detailed description and the drawing, like reference characters indicate like parts.

In Fig. 1, are shown a spare tire l0 and wheel II on its mount in a compartment of a car. Spare tire It rests in a trough I2. The top of the tire abuts a bracket or abutment I3. Trough I2 and abutment I3 usually form a part of the (Cl. 22A-42.24)

2 appointments of the trunk compartment of an automobile body.

Wheel I I is provided with the usual central hub opening I4, at the margin of which is an annular nange or rim I 6.

The tire i@ and wheel I I are held in place by a clamp which includes a main link il, a latch lever I8, and an adjustable sector link or plate I9. Main link Il extends through the hub opening of the wheel. Latch lever I8 is preferably of L- shape and is pivotally attached at the knee thereof to one end of the link Il by a pin 2l. One arm 22 of the latch lever forms a handle, while the other arm 23 thereof has .a jaw engageable with ange l5 of the wheel I I.

As shown, main link Il is provided with a hook 24 at the end thereof remote from pvot pin 2l. Hook 24 extends through an opening or slot 2S in sector plate I9 and engages one side of slot 26.

Sector plate I9 is pivotally mounted on a bracket 2l' that is attached to the vehicle. Slot 26 is arcuate but not concentric with the pivot 28 of plate I9, as the radius R increases in length between points A and B at opposite ends of the slot. The side of the opening engaged by hook 2d is provided with a plurality of spaced notches 29 in which the hook 2d is received. The distance from pivot 23 to the base of the respective notches between points A and B increases so that the eifective length of the link comprising plate I9 and main link Il may be adjusted by moving hook 24 from one notch to another. As shown in Fig. 1, the upper end of slot Z6 is enlarged as indicated at 38 to facilitate removal of the hook from slot 26, if desired. The notches below the upper end of slot 2S are suciently narrow that the hook can not be removed from slot 26 unless it is'in the enlargement.

As shown in Fig. 1, main link Il is of L-shape and hook 24 is at the inner end of arm 3l thereof. The end of outer arm 32 carries pivot 2i. Outer arm 32 is of substantially the same length as the jaw carrying arm of latch lever I8 so that, when the latch lever is advanced to the position shown in full lines in Fig. 1, jaw 23 engages the flange at the hub opening of the wheel, and holds the nange against the central portion or bend of the main link. When the spare tire and wheel are to be released, latch lever i3 is swung to the position shown in dot-dash lines at Ita to release the wheel. Then, the wheel and tire can be moved to the left with the hub opening of the wheel passing over 'the main link and latch lever.

The clamp can quickly and easily be opened or closed to release or clamp the spare tire and 3 wheel. When the clamp is closed, the spare tire and wheel are firmly held in place. If it is found that greater or lesser tension on the clamp is required, hook 24 can be moved along the slot in sector plate I9 to whichever position gives the desired clamping pressure.

In Figs. 3 and 4. is shown a clamp which includes a main link 34 and a latch lever 36. Latch lever 36 is pivoted at 31 to one end of main link 34. The other end of main link 34 is formed into a clevis, as shown in Fig. 4, and is pivotally connected by a pivot pin 31' to the head of a stud 38. Stud 38 is threaded into a vehicle frame member 39, only a portion of which is shown. The clamp illustrated in Figs. 3 and 4 operates in the same manner as does the clamp shown in Figs. 1 and 2. When the clamp is in the position shown in Fig. 3, a wheel 4| is clamped firmly in place. When it is desired to release the Wheel, latch lever 36 is swung counterclockwise upon its pivot to cause the clamp to be released. If the clamping pressure needs to be increased or decreased, the clamp and stud can be turned to advance the pivot pin 31 toward or away from frame member 39 to adjust the tightness of the clamp.

In Fig. 5 is shown a sector plate 43. Sector plate 43 may be substituted for the sector plate shown in Figs. 1 and 2. Sector plate 43 is provided with an arcuate slot 44 having notches 46v along the edge thereof opposite the pivot 41. The notches are denned by teeth 48. Teeth extend generally toward the pivot 41 but also upwardly thereof, so that the teeth are adapted to hold the hook of a main link even when tension on the clamp is released to keep the hook from falling to the bottom of slot 44.

Each of the clamps shown in the drawing and described above, firmly holds a spare tire and Wheel in its mount but can quickly and easily be released to permit removal of the spare tire and wheel.

From the foregoing it will be apparent to those skilled in this art, that various modifications and changes may be made in the illustrated embodiments of the invention Without departing from either the spirit or the scope thereof.

Having thus described our invention what we claim as new and desire to secure by Letters Patent is:
